Rarely mentioned is security, even though there is likely no better example of why devops is something you should be doing. That’s because aside from challenges rising from the virtual machine explosion inside the data center, there’s no other issue that better exemplifies the inability of operations to scale manually to meet demand than web application security. Attacks today are persistent and scalable thanks to rise of botnets, push-button mass attacks, and automation. Security operations, however, continues to be hampered by manual response processes that simply do not scale fast enough to deal with these persistent threats. Tools that promise to close the operational gap between discovery and mitigation for the most part continue to rely upon manual configuration and deployment. Because of the time investment required, organizations focus on securing only the most critical of web applications, leaving others vulnerable and open to exploitation. Two separate solutions – DAST and virtual patching – come together to offer a path to meeting this challenge head on, where it lives, in security operations. Through integration and codification of vetted mitigations, persistent threat management enables the operationalization of security operations. A New Operational Model DAST, according to Gartner, “locates vulnerabilities at the application layer to quickly and accurately give security team’s insight into what vulnerabilities need to be fixed and where to find them.” Well known DAST providers like WhiteHat Security and Cenzic have long expounded upon scanning early and often and on the need to address the tendency of organizations to leave applications vulnerable despite the existence of well-known mitigating solutions – both from developers and infrastructure. Virtual patching is the process of employing a WAF-based mitigation to virtually “patch” a security vulnerability in a web application. Virtual patching takes far less time and effort than application modification, and is thus often used as a temporary mitigation that enables developers or vendors time to address the vulnerability but reduces the risk of exploitation sooner rather than later. Virtual patching has generally been accomplished through the integration of DAST and WAF solutions. Push a button here, another one there, and voila! Application is patched. But this process is still highly manual and has required human intervention to validate the mitigation as well as deploy it. This process does not scale well when an organization with hundreds of applications may be facing 7-12 vulnerabilities per application. Adoption of agile development methodologies have made this process more cumbersome, as releases are pushed to production more frequently, requiring scanning and patching again and again and again. The answer is to automate the discovery and mitigation process for the 80% of vulnerabilities for which there are known, vetted mitigating policies. This relieves the pressure on security ops and allows them to effectively scale to cover all web applications rather than just those deemed critical by the business. AGILE meets OPS This operational model exemplifies the notion of applying agile methodologies to operations, a.k.a. devops. Continuous iterations of a well-defined process ensure better, more secure applications and free security ops to focus on the 20% of threats that cannot be addressed automatically. This enables operations to scale and provide the same (or better) level of service, something that’s increasingly difficult as the number of applications and clients that must be supported explodes. A growing reliance on virtualization to support cloud computing as well as the proliferation of devices may make for more interesting headlines, but security processes will also benefit from operations adopting devops. An increasingly robust ecosystem of integrated solutions that enable a more agile approach to security by taking advantage of automation and best practices will be a boon to organizations struggling to keep up with the frenetic pace set by attackers.
